I hated Blops 2 when I had Comcast, but since I have switched to Verizon it is MUCH less stressful. Being the bandwidth king in a lobby will counteract a certain amount of unskillfullness (don't think that's a word, actually, but you get my point.). I have been gaming for a couple of years now, and the COD series are the only games I buy/ play. I don't have too much rage at the other players only because there is pretty much a counter to just about anything if you play with a little diversity. Getting spam sniped is usually handled by an MK-48 target finder and lots of spray. Snipers HATE getting long shot with LMGs lol. If they are still too quick for me or running cold blooded, I will try an SMG and lightweight/ EC and run to the other side of the map and rape em from behind while they are zoomed in. Close quarters combat snipe? Remington long barrel/ laser combo will cut that down pretty quick. The more you play, the easier it is to figure out what works well against things.
I spend too much time playing this but it's the only one I like right now. I am master prestige and most guns diamond. It's so fun to hear the lobby cry when they get wrecked lol. I dunno, I just think it takes a LOT of PT to get to the point where it's really fun. If you don't have the time to put into it, you may not enjoy it, but I do.
